26 Jimbodiddley 4 months ago I've owned 2 electromatics. My old 5120 was solid when it came to tuning stability. Of the three elec. guitars I then owned (the others where an American Standard Tele and a limited edition John Lennon 1965 Casino), the 5120 was the most stable - and it was the only one with a Bigsby!My current 5422TG, however, is giving me tuning stability problems. It seems to like 11s more than 10s, but I still have problems with the bass E and A strings - which I assume is a problem with the nut, especially since they're going sharp.
